Upgrade without paying for both

[REDACTED]

So I just bought basic internet protection for a year at $20, but given the use of my computer lately, I thought it might be useful to try out premier, which shows itself at $29.99 at the moment. How would I go about upgrading and only paying the difference, or getting my money back so I'm not paying for both subscriptions? Thanks, any help appreciated!

Never heard of "basic internet protection", do you maybe mean avast! Pro or IS..??

Ah, apologies, I meant Internet Security, which is in the store at $19.99. I thought I saw something about a 30 day money back policy, but wasn't sure how to go about that?
